Both inertial and viscous rope coiling can be seen as a thin stream of honey piles up.

A falling stream of corn syrup exhibits unstable rope coiling. Original music by Alexander White.

Dyed streams of honey and corn syrup coil unstably. Original music by Brian Mulligan.

A falling stream of honey piles up in unstable rope coiling, color-inverted.

A stream of Elmer’s Glue dropped into water is held at the surface. Here the image is mirrored by the surface and then flipped vertically.

A stream of Elmer’s Glue falling into water forms convoluted shapes. Surface tension holds glue at the surface during a rope coiling instability for a short time.

Streams of Elmer’s Glue fall through water.

Streams of Elmer’s Glue in water diffuse into clouds.

Two simultaneous instabilities: food dye and corn syrup exhibit a Marangoni instabiltiy, and dyed water injected into the corn syrup show the Saffman-Taylor fingering instability, all in a Hele Shaw cell.

A thin layer of dyed corn syrup is rippled by additional fresh water flowing over the surface.
